Wired Keyboard Does Not
Function Properly
• Some or all keys on the
keyboard don’t work
• Eject key or Caps Lock key
doesn’t seem to work
• Some keys don’t work as
expected
1. The system has 4 USB ports on the rear of the
computer. Make sure to try each port to isolate a
particular port malfunction.
2. Test with a known good wired keyboard to
isolate a failed peripheral issue.
3. Test the keyboard on another Mac. If it works
here, you may have bad USB port if the keyboard
doesn’t work at all, or a software issue if the
keyboard is working but not as expected.
4. Ensure that all available Software Updates have
been applied to the computer for access to the
latest bug xes.
